Answer: 23 years
Explanation:
From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:
= 364 / 16
= 22.75 years
= 23 years approximately
